CRC Series

CRC’s contain traceable thermal conductivity reference materials for calibration of Non-Steady-State Probes. There are several different CRC types. The geometry of the different types is adapted to fit needles with a certain diameter. Hukseflux is a leading supplier of Non-Steady-State Probes, and is the inventor of the CRC calibration method.

Description

CRC calibration cylinder 1webv1201
The hart of the CRC cylinders is a specially manufactured amorphous plastic reference material (5). (See Figure 1). Contrary to other plastics, this material does not have any directionally dependent thermal properties. In the plastic material a hole is drilled (4), with the approximate outer dimensions (ND Needle Diameter and IL Insertion Length) of the needle that needs to be calibrated.

CRCseriesThe plastic material is incorporated in a metal protection casing (2). A plug (7) is provided for sealing purposes. In order to guarantee perfect contact between needle (1) and reference material (5), the metal casing is filled with a fluid, glycerol (3). An additional hole (6) is provided in order to be able to perform checks of material stability with thin needle probes. The user is recommended to send the CRC to Hukseflux for a check of material stability every 5 years.
